Coal gasification: the COED process plus char gasification
A conceptual design and an economic study were conducted for a plant to produce 250 million std cu ft/day of pipeline gas, and about 27,000 bbl/stream day of synthetic crude oil, from coal. The plant utilizes the Char-Oil-Energy- Development (COED) coal pyrolysis process along with the M. W. Kellogg Co.'s molten salt process to gasify COED char. The process is based on multi-stage fluidizedbed pyrolysis of coal to produce oil, gas, and char. The oil is hydrogenated to produce a synthetic crude oil, and the gas can be further processed to produce pipeline gas or hydrogen. The char, amounting to about half of the original coal feed, must be utilized efficiently to avoid a serious economic disability to the process. Possible uses for the char include burning as a boiler fuel for power generation or gasification to produce fuel gas. This design utilizes an existing process to gasify the char and to produce high Btu pipeline gas from the combined raw COED and gasification gases. (auth)
